Abstract

A method for providing BGP route updates in an MPLS network is disclosed. The route update is performed at a router having a forwarding information table containing BGP routes and an internal label, and an adjacency table containing BGP/VPN labels and said internal label. The internal label corresponds to at least one IGP route and has an adjacency associated therewith. The method includes updating the adjacency associated with the internal label following an IGP route change.
